Results from an interim analysis of a phase 3 trial of an investigational Ebola vaccine demonstrated 100% efficacy in more than 4,000 adults in Guinea.

“This is an extremely promising development,” WHO Director-General Margaret Chan, MD, said in a press release. “The credit goes to the Guinean government, the people living in the communities and our partners in this project. An effective vaccine will be another very important tool for both current and future Ebola outbreaks.”
